The Project Peg Simons, Volunteer In Park:– GPS’ed the fence line
– GPS’ed & photo-documented potential problem areas
Integration of digital photos with GPS points
Link Photos with Table Records
Why did we choose the method of embedding photos in a geodatabase?
No addition software or extensions required, easy sharing
Provided with data, we were not part of the field process
One Image per Point
Option of managing bythe geodatabase

Decision Time…Managed vs. Not Managed
Managed by the Geodatabase: Sounds Good, Right?
Benefits:– No further need for image management– Automatically moves photos with spatial data
Downsides:– Unstable– Large file size– Always providing photos with the spatial data
Recommendation: Do not have the geodatabase manage the photos.
